# Installation from binary
All downloads come with SQLite, MySQL and PostgreSQL support, and are built with
embedded assets. This can be different for older releases.
**Table of Contents**
{{< toc >}}
## Download
Choose the file matching your platform from the [downloads page](https://dl.gitea.io/gitea/), copy the URL and replace the URL within the commands below:
```sh
wget -O gitea https://dl.gitea.io/gitea/{{< version >}}/gitea-{{< version >}}-linux-amd64
chmod +x gitea
```
## Verify GPG signature
Gitea signs all binaries with a [GPG key](https://keys.openpgp.org/search?q=teabot%40gitea.io) to prevent against unwanted modification of binaries.
To validate the binary, download the signature file which ends in `.asc` for the binary you downloaded and use the GPG command line tool.
```sh
gpg --keyserver keys.openpgp.org --recv 7C9E68152594688862D62AF62D9AE806EC1592E2
gpg --verify gitea-{{< version >}}-linux-amd64.asc gitea-{{< version >}}-linux-amd64
```
Look for the text `Good signature from "Teabot <teabot@gitea.io>"` to assert a good binary,
despite warnings like `This key is not certified with a trusted signature!`.
## Recommended server configuration
**NOTE:** Many of the following directories can be configured using [Environment Variables]({{< relref "doc/advanced/environment-variables.en-us.md" >}}) as well!
Of note, configuring `GITEA_WORK_DIR` will tell Gitea where to base its working directory, as well as ease installation.
### Prepare environment
Check that Git is installed on the server. If it is not, install it first. Gitea requires Git version >= 2.0.
```sh
git --version
```
Create a user to run Gitea (e.g. `git`)
```sh
adduser \
--system \
--shell /bin/bash \
--gecos 'Git Version Control' \
--group \
--disabled-password \
--home /home/git \
git
```
### Create required directory structure
```sh
mkdir -p /var/lib/gitea/{custom,data,log}
chown -R git:git /var/lib/gitea/
chmod -R 750 /var/lib/gitea/
mkdir /etc/gitea
chown root:git /etc/gitea
chmod 770 /etc/gitea
```
**NOTE:** `/etc/gitea` is temporarily set with write permissions for user `git` so that the web installer can write the configuration file. After the installation is finished, it is recommended to set permissions to read-only using:
```sh
chmod 750 /etc/gitea
chmod 640 /etc/gitea/app.ini
```
If you don't want the web installer to be able to write to the config file, it is possible to make the config file read-only for the Gitea user (owner/group `root:git`, mode `0640`) however you will need to edit your config file manually to:
* Set `INSTALL_LOCK= true`,
* Ensure all database configuration details are set correctly
* Ensure that the `SECRET_KEY` and `INTERNAL_TOKEN` values are set. (You may want to use the `gitea generate secret` to generate these secret keys.)
* Ensure that any other secret keys you need are set.
See the [command line documentation]({{< relref "doc/usage/command-line.en-us.md" >}}) for information on using `gitea generate secret`.
### Configure Gitea's working directory
**NOTE:** If you plan on running Gitea as a Linux service, you can skip this step, as the service file allows you to set `WorkingDirectory`. Otherwise, consider setting this environment variable (semi-)permanently so that Gitea consistently uses the correct working directory.
```sh
export GITEA_WORK_DIR=/var/lib/gitea/
```
### Copy the Gitea binary to a global location
```sh
cp gitea /usr/local/bin/gitea
```
## Running Gitea
After you complete the above steps, you can run Gitea two ways:
### 1. Creating a service file to start Gitea automatically (recommended)
See how to create [Linux service]({{< relref "run-as-service-in-ubuntu.en-us.md" >}})
### 2. Running from command-line/terminal
```sh
GITEA_WORK_DIR=/var/lib/gitea/ /usr/local/bin/gitea web -c /etc/gitea/app.ini
```
## Updating to a new version
You can update to a new version of Gitea by stopping Gitea, replacing the binary at `/usr/local/bin/gitea` and restarting the instance.
The binary file name should not be changed during the update to avoid problems in existing repositories.
It is recommended that you make a [backup]({{< relref "doc/usage/backup-and-restore.en-us.md" >}}) before updating your installation.
If you have carried out the installation steps as described above, the binary should
have the generic name `gitea`. Do not change this, i.e. to include the version number.
### 1. Restarting Gitea with systemd (recommended)
As we explained before, we recommend to use systemd as the service manager. In this case, `systemctl restart gitea` should be fine.
### 2. Restarting Gitea without systemd
To restart your Gitea instance, we recommend to use SIGHUP signal. If you know your Gitea PID, use `kill -1 $GITEA_PID`, otherwise you can use `killall -1 gitea`.
To gracefully stop the Gitea instance, a simple `kill $GITEA_PID` or `killall gitea` is enough.
**NOTE:** We don't recommend to use the SIGKILL signal (`-9`); you may be forcefully stopping some of Gitea's internal tasks, and it will not gracefully stop (tasks in queues, indexers, etc.)
See below for troubleshooting instructions to repair broken repositories after
an update of your Gitea version.
## Troubleshooting
### Old glibc versions
Older Linux distributions (such as Debian 7 and CentOS 6) may not be able to load the
Gitea binary, usually producing an error such as `./gitea: /lib/x86_64-linux-gnu/libc.so.6:
version 'GLIBC\_2.14' not found (required by ./gitea)`. This is due to the integrated
SQLite support in the binaries provided by dl.gitea.io. In this situation, it is usually
possible to [install from source]({{< relref "from-source.en-us.md" >}}), without including
SQLite support.
### Running Gitea on another port
For errors like `702 runWeb()] [E] Failed to start server: listen tcp 0.0.0.0:3000:
bind: address already in use`, Gitea needs to be started on another free port. This
is possible using `./gitea web -p $PORT`. It's possible another instance of Gitea
is already running.
### Running Gitea on Raspbian
As of v1.8, there is a problem with the arm7 version of Gitea, and it doesn't run on Raspberry Pis and similar devices.
It is recommended to switch to the arm6 version, which has been tested and shown to work on Raspberry Pis and similar devices.

please remove after fixing the arm7 bug

### Git error after updating to a new version of Gitea
If during the update, the binary file name has been changed to a new version of Gitea,
Git Hooks in existing repositories will not work any more. In that case, a Git
error will be displayed when pushing to the repository.
```
remote: ./hooks/pre-receive.d/gitea: line 2: [...]: No such file or directory
```
The `[...]` part of the error message will contain the path to your previous Gitea
binary.
To solve this, go to the admin options and run the task `Resynchronize pre-receive,
update and post-receive hooks of all repositories` to update all hooks to contain
the new binary path. Please note that this overwrites all Git Hooks, including ones
with customizations made.
If you aren't using the Gitea built-in SSH server, you will also need to re-write
the authorized key file by running the `Update the '.ssh/authorized_keys' file with
Gitea SSH keys.` task in the admin options.
